io all whom 'it may concern:

Bc it known that I, ALnnnr W. DE NEEN, a citizen of the United States.residing at St. Joseph, in the ,county of Buchanan and,J State of.'ilissouri` have invented certain new and useful Improvements inShow-Case Refrigerators, of which the following is o specification.reference being had to the acf compairviug drawings.

This invention is an improved displa7 refrigerator for use in displayingmeats and other provisions, and also refrigercting the tive andwholesome Condition.

@ne object of my invention is to provide :in improved refrigerator ofthis class which is exceedingly ctlicient, in which all parts are accesle, so that the refrigerator may bereadiiy Kept in a Clean and sanitarycondition, and which is extremely simple, may be manufactured at minimumcost, and consumes but a niinin-:inn quantity of ice. Another object ofmy inventionr is to effect improvements in the construction of theconduit through which the refrigerated air from the ice box is blown tothe case or coinpartlnent in which the provisions are kept.

vAnother object is to Jrovide improved means for deliecting the last ofair from the refrigerating chamber to `the ice box, and through andaround the ice in theiee box so as to cause the ice to etl'ect theretrig era-ting or cooling of the air while the saine is passingthroughthe ice box, and before it reaches the blowing fan..

A further object of my invention is to effect improvements in theconstruction of the regulating valves.

With the above and other objects in view, the invention consists 'in theconstruction, combination and arrangement of devices In the accompanyingdrawings-Y-Figure l is a vertical longitudinal central sectional view ofa display refrigerator const ructed in accordance with my invention.Fig. :2 is a horizontal sectional view of the saine ou the planeindicatori by the line a-o of Fig. l. Fig. 3 is a transverse sectionalview of the same on the plane indicated bv the line b-b of Fig. 1. Fig.4 is a detail sectional view on the plane indicated by the line c-c ofFig. 1.

In the embodiment of my invention here shown, l provide an ice box 1, onone side of which is a case 2, providing an upper refrigerating chamber3, and a lower chamber 4, the upper chamber 3 being preferably, and ashere indicated, a. glass case having end poptions 5, 6, of cabinet.work1 and the lower compartment 4 forming a counter, the top of thecounter indicated at 7, being preferably a marble slab which also formsthe horizontal partit-ion.

In the rear WallV of the case forming the refrigerating compartment, 3,are openings provided `with doors 8 which enable access to the articlesin the'said refrigeratiug vompartinent and on the counter to be had.' l

would have it; understood that in v improved h display refrigerator maybe made of any suitable material and finished in any suitable manner,and'that tbc saine may bc ofv any suitable size, and tbc variousl partsthereof, or" any suitable proportion.

The ice box l is provided with a lid i? which is hinged atonc side as atl0. plat(- 11 is spaced from the lower side o' the saidl lid and iscarried thcrcbv. the said plaie is prete 'abbv made of short nielal andis here shown as suspended from the lid il and .supported at a Suitabledistance below the sano: by metal straps l." ..theuppvr ends of whichare outtm'ncd and secured to the undcr i ie of the said lill.l theirlower ends being; iuiurncd and secured to the plate at the side edgesthereof.

The lower side ofthe said opening is above the counter 'l' which forms the bottom. of therefrigeratiu* chamber. and a detiecting plate 17 which 1s inclined, isattached to tl-e inner end wall of the ice box at a no'n c-linrid t` aith the lower side. of the .will opening lf?. one enfl of the saidinlira-f ola resting on the rotuzfer T or bottom of the, refrigerados*chamber. .hn opening lll iu the `:aid 'nne end wall ol` the ice ho:'-wahlislrw como:eaniration between the louer '.art'ion thereof and thelower eot'tgiarttneui -'t of the ease 2. lle said compartment is dividedh r a vertical 'partition lf), into an aiirintain @handler L'O, and itdat?. gir-'aber l. lo the rear all of thAm air intake Leber is an meningnrovidet'l ith a door -shapeel spx-vaders 23 are .sfeer-ed orali-f upride of the plate Il, and dispwed with t poi`l tud ends opito ite theone? f l". heir bases or broadened #nelse:-;tend n ,o the outer tige ofthe said plate. 011e or more of these spreaders may be used. :rnd wherea plurality of them are employed. as it; the iorin of the invention hownherewith, their broadet'ied ends are spared somewhat apart, and are alsospaced from the sides oi the plate 11. which forni the .side walls ofthe spreadiuo' chamber.

suitable blower il which is here shown as an elet-trie fan, operates inthe intake end Q of a duct Bti which is preferably made of suitable'sheet metal.' The. said duet is provided with an npturned portion Q7which extends through the partition Y and termimitt'fs in a reverselybent nozzle 2S which is lo aied in the outer end portion of therefrigerating chamber.Y is contracted in width vertically, is broadenedhorizontally. as shown in Vig. 2, so that the 'discharge end of the saidnow/,le extendsl practically" across the rcfrigerating chamber from thefront 'to the rear wall thereof. The under i .side of the discharge' endof the said nozzle bears on a cleat or partition Ql which lies on thelzorilontal partition T and serves to prevent any article in therefrigeraling chamber from getting into the nozzle or into the duet 26.the .main portion of the duet fl tapers from its intake end to itsjoint. with the uptaz'ned bend the intake portion 25 of the duet beineItapered to a greater extent than the internadiate por` nozzle` formed hythe bend 2T is eontraeted. pair of dellectin'f valves 3l are disposed inthe nozzle 28. lfl-aeh of these deflection valves is preferably asubstantially oblong! ret-tangiilar sheet metal plate. Their front endsare pivotally connected together as at '32, their pivotal axis beinglvertical. The

sai(t tieileeting valves converge to 'ard the throat or narrow end ofthe nozzle, and they are movable toward and from each other so that theym: j be disposed at any desired distance apart. Any suitable means maybe employed to adjust the said deflecting valves. They ate here shown aseach provided with :i rack bar 33, between which is mounted a pinion 34whieh'cngages both ,of said rack bemand has its lz-earugs as at.

371. and is provided with a head or other suitable device lt on itsshaft, whereby the pinion may be turned and caused by eonetion with therack bars to adjust` the said delleetng valves as may be required.

A valve 36' is located in the opening 1G, and extends across the saidopening, -the seid valve being horizontal so that the valve may be movedangularly in a vertical plane, to open or close the opening 1G to anydesired extent. Any suitable means may be empl ved for operating thisvalve. l herein show for this purpose a rod 38. which leads to a pointnear one of the doors tl, operates in a. guide 39, and is provided withrack -teetlt'40 any lone of which may beV engaged willi a pin 40* so asto secure `the rod. and hence also the ,said valve 3G, in :un: desiredadjusted position.

lhe operation of my improved display refrigerator is as follows: Asuitable uantity of ice. either with or without'J sa t, is placed in theice box and on the rack 14. The blower 24 is set in operation and thevalves :t1 and 36 are moved to open position. The blower draws air fromthe ice box and forces the same through the duct 26 into therefrigerating chamber, and the exhaust, or suction in the ice box,caused by the operation of the blower, causes the air from therefrigerating'ehamber to pass down through the ice box, and hack intothe duct "Z6, so 'that a constant. circulation of air in the directionoli the arrows, is caused through the ice box, the duet and therefrigerating chamber, the air passing through the refrigerating chamberin a blast. As the air is passed 'through the iee box and in Contactwith the surfaces of the ice, it is rendered extremely cold, The. coldair is sucked by the blower from the ice box through the suction chamber:20, and blown through the duct 26. Owing to the fact that the said duettapers from its int-alte end to the contracted throat of the nozzle, itsvelocity is greatly increased, and hence it issues from the nozzle f, ina strong blast which sweeps through the tion 730 of the said duet. Thethroat; of the .strength of'the blast of cold air maintained through therefrigerating chamber and the exhaust. or suction action of the blower,in and through the iee box, the cold ai'r of the refrigerating chamberdoes not escape therefrom when the doors 8 .f ze opened. In prac. ticaltests which I have made, thermometers i apart or adjusted asmay berequired to dein the refrigeratingI ehambet` have indicated no inert-aseot' tempera-ture in the refrigeratiutf chamber when the doors areopened.

'l' ie tluet chamber 21 is filled with a suit.- able heatnonieonductingpacking 3S around the dut-t 2G. The valves 31 may be spread ileet tbeair to opposite sideso the refrigeratinpr chamber and prevent it frompassing through the center of the chamber,

The spreader or spreaders 23 in the spreading chamber operate inconnection with the plate t1 as baliies to deflect the air currentto'opposite sides of the refrigerating eluunbrand prevent it frompassing by the .shortest course through the center thereof,

and this secures an equal distribution of the air to all parts of theice-box so that it acts upon all of the exposed surfaces of the ice inthe ire'box and hence is cooled by the ice to the maximum extent.
